Warren J. TURNIBULL, DECEASED, BY .iosiirii a. SULLIVAN AND EMILY D.TURNBULL, EXEGUTORS, oiinnw ORLEANS..LOUISIANA.. i i

To all whom it may concern: f

Be it known that we, Jos iri T. SUnLivAN and EMILY DELANEY. :TURNBU L,citizens of the United States, and residents of New Orleans, in theparish of Orleans and State.

of Louisiana, have been appointed executors of the estate of VALTERTJ.TURNBULL,

deceased, who during hislifetinie invented certain new and usefulImprovements in Slat Conveyers, of whichjthefollowiiig is.

a specification.

This invention isan improvement in slat the conveying surface or" whichis so fashioned as to present a substantially continuous flat surface,thereby preventing loss of material conveyed whileatfthe same time beingcapable of passing around the driving wheels at the end of the conveyer.

A further object of theyinvention is to provide means at the sidesoftheconveyer for preventing the spilling of the contents of the conveyerfrom thesurface thereof, said means consisting of a series ofinterlocking side members, as will be hereinatter described. 1

Other objects and advantages will appear in the following specificationand the novel features of the device will be particularly pointed out inthe appended claims.

The invention is illustrated in the accompanying drawings forming partof this application in which- Figure 1 1s a side viewoi one end of. the

conveyer a portion being shown in section, Fig. 2 is a perspective viewof one of the units, Fig. 3 is a sectional view along the line 3-3 ofFig. 1 Fig.5 a longitudinal sectional view through afportion of thedevice, Fig. 5 is a plan viewof amodified form, Fig. 6 is a sectionalongthe line of Fig. 5, and Fig. 7 is a perspective View of one of theunits of the modified form.

In carrying out the invention use is made of a series of units or slatslike that shown in Fig. 2. Eachof thesej slatscomprises a body portion 1having upstanding flanges 2 at its ends. One edge of the body portion 1is provided with a downwardly extending flange 3 which is preferablyformed integral with thebody portion, being bentias Specification ofIetters Patent. Application filed April 22, 1914. Serial No. 833,723.

shown'inthe drawing. At each end ofthe flange .3 180.11 extension 1which is bent at right angles to the flange 3 and parallel with theupstanding end 2. The extension thas an upwardly extending arm 5provided at its top with a portion 6 bent over in the form of a hookwhich engages the upper edge ofthe endinember 2; a

The units are connected together. by means of rods 7. These rods 7 passthrough the flanges .4: near their junction with the arms 5. As will beseen from the drawing the units overlap so that the rods also passthrough the members 1 of the adj acent unit close to the flange 3. Aswill be seen from Fig. 1, the upstanding end 2 of one unit, alsooverlaps the upstanding .end of tlle itdjik cent unit. Moreover the end2 of one unit at tea oat. .1914. 1

passes between the arm fi'ofthe adjacent unit and the end 2 oftheadjacent unit.

Secured to the ends of the rods? are 1 flangedrollers or wheels 8 whichare de-.

signed to run on a track 9 (see Fig. 1). 1 A

sproclzet wheel 10 is mountedon a shaftll and 1s designed to turn inthe-direction shownjby the arrow in Fig. 1. The recesses 11*. ofthesprocket wheel are designed to Vith the sprocket receive the rollers.wheel revolving, as shown inFig. 1 itwill beapparent thatas the unitspass around so; i i

the wheel theywill assume the angular I sition shown in Fig. 1, thisbeing the dump-j ing end of the conveyor. Thus units which are on theupper side of the device at any given moment form a substantlally flatem:

face. In Fig. 4 I have shown therelative" positions of the overlappingunits. It will be understood, of course, that the slats are shown ofgreater thicknessthan they would be in reality. This is for-purposes ofillustration. As amattei' of fact the surface of the conveyer would besubstaiitially flat on the upper part where the matteris being carried.a

The provision of a devlce described as abovehas numerous advantages. Inthe first placetheslats are positively locked together so as to preventany escape of material car-1 ried thereby. This is true of the sides as.1 well as of the bottoms. Theflanges 3 constitute brace members. Therods 7 afford. not only axles for the Wheels or rollers 8, but alsohinges about which the units may turn when they reach the sprocket wheel10. j The manner of making the units so as. to

In-Figs. 5, 6 and 7 we have shown a modifled form of the device. In thisforineach unit comprises a body portion 12 having a laterally extendingflange 13 on one edge and end flanges 14 which project beyond the flange13, as shown in Fig. '7. The units are assembled so that the bodyportions 12 overlap. through openings 16 and 17 in the flanges 16 Whenassembled the device has the appearance of that shown-in Fig. 6 in whichthe rods 15 pass close to the flanges 13 of the adjacent unit. Rollersor wheels 18 are provided which permit the conveyor to pass aroundsprocket wheels like that shown at 10 in Fig. 1. In this case, as in theform described in Figs. 1 t t inclusive the end flanges 14 of one unitalso overlap the end flanges of the adjacent unit so that the rods 15pass through these overlapped flanges. In this form of the device thetop part of the conveyer is substantially flat, but the units freelymove around the sprocket wheel and between the sprocket wheels againassume the position shOWn in Fig. 6. The devices described areespecially adapted to carry material such as fine sand, ore pulp, or anyother material which has a endeney to leak through the cracks andcrevices of the ordinary conveyer. The units are simply and cheaplymade, but are of great strength owing to the mutual reinforcing of themembers when in their locked position. I

Claims: 1. In an endless conveyer, a plurality of units, each unitcomprising a body portion having upturned end flanges, and a downwardlyturned side flange, said side flange having laterally bent extensionslying substantially parallel with the upstanding end flanges, saidparallel flanges being provided with upwardly extending arms bent attheir tops to engage the tops of the upwardly extending end flanges.

2. In an endless conveyer, a plurality of units, each unit comprising abody portion having upturned end flanges and a downwardly turned sideflange, said side flange having laterally bent extensions lyingsubstantially parallel with the upstanding end flanges, said parallelflanges being provided Rods 15 are provided which pass pivot rods.

with upwardly extending arms bent at their tops to engage the tops ofthe upwardly extending end flanges, a pivot rod carried by said parallelflanges near one end thereof, and a second pivot rod carried by saidparallel flanges underneath the body portion and adjacent to thedownwardly extending flange.
